WOVEN PILE FABRIC.

Specification of Letters Patent.

Original application filed December 7, 1917, Serial No. 205,938. Bividedand this application filed May 10, 1918. Serial No. 233,626.

To all whom it may concern:

Be it known that I, FREDERICK O'r'r, a citizen of the United States,residing at Norristown, in the State of Pennsylvania, have invented acertain new and useful Improvement in Woven Pile Fabrics, whereof thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to warp-piled fabrics of the double plush classwhich, when separated, form two textures which are alike.

The peculiar arrangement of the pilev threads in accordance with myinvention not only produces pile facings of uniform density for therespective textures, but effects a more general interlocking of thosethreads with the backing threads, than in ordinary fabrics of saidclass, and, consequently, renders my improved fabric more firm anddurable than such ordinary fabrics.

Moreover, in such ordinary fabrics the ground threads are so arranged asto form plain cloth backs for said textures; whereas, the ground threadsin my fabric may be arranged, as hereinafter described, to form backingcloths for the respective textures, which are twilled, to render themmore pliable than plain cloth, for furniture coverings and draperies.

My invention includes the various novel features of construction andarrangement hereinafter more definitely specified.

In the drawings: Figure I is a'diagrammatic plan view of one patternblock of a double. fabric embodying my invention; looking downward uponthe back of the upper texture shown in Fig. II.

Fig. II is a diagrammatic longitudinal sectional view of the singletexture, the back of which is shown in Fig. I; taken on the line II-IIin, that figure, to show the relatively staggered course of a pair ofground warp threads. Fig. III is a plan view looking downward on theback of the upper texture shown in Fig. IV. Fig. IV is a longitudinaledge view of said pattern block of the double fabric, showing thegeneral course of the warp pile threads. Fig. V is a diagram indicatingthe order of shedding of both the ground and pile threads of saidfabric.

In Figs. I and III, the horizontal rows of squares represent warp endsand the vertical rows of squares represent picks of weft. Accordingly,in Fig. V, the horizontal lines represent warp ends and the verticallines represent successive shedding operations; and the order in whichthe respective warp ends are drawn up in the shedding operationsrepresented by Fig. V is indicated by the m marks at the junctions ofthe lines in said figure.

Said fabric is conveniently made with four backing 'ends and four pileends in one dent; and with six backing heddles, shedded in the orderindicated in- Fig. V; wherein the horizontal lines 1 to 6 inclusiveindicate six warp ground threads, and the horizontal lines 8 to 13inclusive indicate six Warp pile threads. The vertical lines in saidfigure indicate the twenty-four shedding movements necessary to completethe pattern; each of said threads being raised to the surface of thefabric in the order indicated by the marks as thereon, considered fromleft to right in said figure. Said threads are thus identified in theother figures, which show patterns, each including twelve pile threads,which may be repeated transversely with respect to the respectivefabrics, to any desired width, It may be observed that said patternincludes three series of said pile threads, each including twopairs ofpile threads shedded alike, but unlike the adjoining series; but thatsaid pile threads are divided in groups of two,

transversely with respect to the fabric, by

respective groups of "ground threads.

The fabric herein claimed is thus distinguished from that claimed in myapplication Serial No. 205,938, of which this application is a division;the specific claims in that application being limited to a fabric inwhich the pile threads are divided in groups of four; transversely withrespect to the fabric, by respective groups of ground threads. Moreover,in that case. I prefer to arrange the ground warp threads in groups eachconsisting of four threads, dividcd in pairs to the respective textures,the members of which pairs, instead of being simultaneously shedded upand down are shedcled successively in relatively staggered relation in atwo up and one down manner with reference to the backs of the textures.On the cont'rary,in the present case, I prefer to arrange the groundwarp threads in" groups 15, each consisting of two threads, dividedsingly to the respective textures, but in the same relative staggeredrelation, and two up and one down manner, with reference to the backs ofthe textures. However, I do not desire to limit myself to such specificarrangement of the ground threads.

In the patterns shown in Figs. I to V, the groups 15 of said warp groundthreads 1 to 6 extend singly and alternately, between said pile threadpairs which are shedded alike, and between those which are sheddedunlike; such arrangement being thus distinguished from that claimed inmy copending application Serial No. 205,938, wherein the Warp groundthreads extend only between the pile thread pairs which are sheddedalike.

Said warp threads are shedded in a reclining twill in the backs of therespective textures; thus affording a desirable degree of pliability,despite the firmness of the fabric. However, as they present acorresponding twilled effect in the respective pile facings formed bycutting said double fabric between its backing textures, it is to benoted that the twill is less visible in the specific form herein claimedthan in the form claimed in my copending application Serial N 0. 205,938aforesaid. However, I do not desire to lim1t all of my claims to suchtwilled arrangement or effect.

Therefore, I do not desire to limit myself to the specific constructionand arrangement herein set forth, as it is obvious that variousmodifications may be made therein, without departing from the essentialfeatures thereof, as defined in the appended claims.
